Always a power encounter strong telescopes on the enigmatic objects called quasars. They are the nuclei of active galaxies from the youth of the universe. Over short periods of time they will glow extremely bright and are so huge distances visible with “short” in the cosmic sense, tens of millions of years can include.
quasars are probably made up of a black hole surrounded by a disk of luminous Material. The particular: Some of the black holes are 13 billion years old – only slightly younger than the universe itself. Astronomers puzzles, such as they could collect within a few million years, so a lot of mass.
Actually, is not likely to give it to you
actually, it is not likely to give that old black holes. So far, astronomers believed that black holes occur when a star runs out of fuel and it explodes in a Supernova. The now discovered black holes were formed shortly after the universe itself, writes an international team of researchers in the journal “Nature”. In such a short time is impossible, a star can arise and die again, argue the researchers. But where does the mass Snatchers?
study author John Wise from the Georgia Institute of Technology, says: “In this study, we have discovered a completely new mechanism that triggers the formation of massive black holes.” The answer lies in the gas clouds that lead to the formation of galaxies, so-called Halos.
More on the topic of Black holes is the last work of Stephen Hawking
published Thus shaped Dark matter Halo-like formations that grew extremely fast. The formation of stars was under these conditions is impossible. For black holes, however, they were ideal. Because of the enormous growth of unstable Gasgebilde, the collapsed eventually due to their own gravity emerged. The early massive black holes have skipped, therefore, the formation of stars.
Supercomputer simulates early universe
For the study, the researchers used a Simulation of the early universe, which had been calculated by the Supercomputer “Blue Waters”. In the huge data set, the researchers discovered ten Halos, in which actually star should have been. To clouds of gas seemed to be empty. In a further Simulation with the help of a supercomputer, the researchers offered the time until shortly after the big Bang. Where “short” is still a good 270 million years means.
“As we looked at the closer, we realized that these areas lived in a period of extremely rapid growth,” says Wise. They are convinced that such Halos occur much more frequently than previously thought. The researchers now want to find out how this gigantic mass of eaters continue to develop. But you still do not know exactly where these black holes are today.
